The Mexican Stock Exchange (BMV) experienced a decline of 0.59% to 70,934.55 points, primarily driven by downturns in the mining sector as metal prices took a hit. This decline occurred shortly after the market opened, coinciding with Wall Street returning to activity after a lengthy weekend. Investors are closely monitoring the upcoming fourth quarter earnings reports, which are expected to play a crucial role in market direction.

Among the hardest hit was Grupo México, a leading global copper producer, which saw a drop of 3.18% to 197.23 pesos, along with Industrias Peñoles, the world’s largest silver producer, whose shares plummeted by 2.77% to 1,010.04 pesos. These declines reflect the broader trend in the mining industry amidst fluctuating commodity prices, emphasizing the sector's vulnerability to external market pressures.

In contrast, Grupo Aeroméxico saw positive movement with its shares increasing by 6.29% to 32.95 pesos following the release of its quarterly results. This performance stood out amid the general market decline, showcasing the mixed responses of different sectors in the face of economic uncertainties as the market looks ahead to significant earnings announcements in the coming weeks.
